Circuit theory for crossed Andreev reflection and nonlocal conductance
arXiv:0709.4020 · doi:10.1007/s00339-007-4194-3
Abstract
Nonlocal currents, in devices where two normal metal terminals are contacted to a superconductor, are determined using the circuit theory of mesoscopic superconductivity. We calculate the conductance associated with crossed Andreev reflection and electron transfer between the two normal metal terminals, in addition to the conductance from direct Andreev reflection and quasiparticle tunneling. Dephasing and proximity effect are taken into account.
